little help!
K my 2000 Cherokee 4.0 is missfiring and chugging on cold start up. The longer I run it the more often it will randomly go back to normal. Then it will start chugging again? And help would be appreciated!

If its a missfire then it is most likely In your IGNITION system somewhere, Try swaping a coil and see if the code goes from cylinder 4 to what ever cylinder you swaped it with. Probally a bad coil pack. Also check all you connections and make sure they are good. Dont forget to check your grounds too
